Hi, 1. The decelaration is used to calculate the safe gaps, so it is always important unless you disable all security checks 2. The backlog is caused because the gap is not considered safe. And yes, one possible solution is to reduce tau to allow for smaller safe gaps. Best regards, Michael Am 02.02.2018 um 14:54 schrieb 杜 伟强: > Hello: > > 1.
